Project 22-250 AI

I am working on a project and am thinking about doing a 22-250 AI with 75gr A-max bullets for a little long range shooting/chucking. I have a 1:9 twist 26" Savage takeoff barrel from my .223 that shoots lights out to rechamber. I am in the process of getting a Savage action with accutrigger and .473 bolt face to use so it should mate up well. I am also concidering a 220 Swift Improved or a 22-243 wildcat. Pushing a 75gr Amax to around 3500-3600fps yields some amazing ballistics!! Any thoughts on this setup? Any other calibers you would reccomend?

You might want to think about a 26" to 28" inch 1-8 or 1-7 twist with that cartridge, using the 80gr & 90gr for LR work... It would a great combo.

Re: Project 22-250 AI

I rechambered a Savage 22-250 in 22-243 with the factory slow twist barrel I was able to achieve 4600 fps with a HOT (little to hot) load behind a 40grn blitzking. The accuracy is great & the rechamber job cost me ~$150, hard to beat that combination. The Swift improved, as far as I have heard, is a notorious barrel burner (not that the 22-243 isn't). I'd stick with the 22-243 with a fast twist & go with the 75grn A-Max, that combination is wildly successful here in north eastern WY, it's proved to be a great round.

Re: Project 22-250 AI

My rifle still has the factory 22-250 Barrel, so unfortunately the twist is too slow to stabilize the heavy high BC bullets. I ordered my 3-die set from Redding which was readily available, brass is Nosler 243 win, I use Fed 210M primers & started loading with a 40grn Sierra blitzking with Ramshot hunter, I was able so safely achieve 4600fps before showing pressure signs. I don't have the load data here in front of me but I started by utilizing 220 swift data & worked up from there if my memory recalls correctly. I have left both the blitzking & the Ramshot powder in favor of a Sierra 53gr Match bullet & am in the process of trying various powders for optimal accuracy. Velocity is always there but accuracy has been finicky at this point ~1moa to this point, of course @ +4000fps I can certainly understand why!! This is a new caliber to me as well, the gents i know are using a fast twist bbl with the Hornady 75gr A-Max With either Retumbo or RL-25, most are getting ~3500fps with this combo. I know this isn't much info to start with but I hope I can help you make your decision.

Re: Project 22-250 AI

I have a Savage I built to a 22-250ai. I used a 1-8 douglas barrel and am using 75gr v-maxes. I've been impressed with the accuracy and the way it rings the steel plates compared to my 223's. Unfortunately I haven't had a chance to chrono it yet.
